How to Perform a Trigger Point Injection

Trigger points are tight bundles of muscles, which cause widespread pain, muscle weakness and may twitch in reaction to pressure. They are mostly associated with myofascial pain syndrome and fibromyalgia. Trigger point injections have been found to be one of the most effective treatments for the condition, particularly when used in conjunction with exercise, heat and other therapy, and medication.

  Re-insert needle in every direction around the trigger point, until the twitch response has stopped.
